Question

Under what condition(s) is the magnitude of average velocity of an object equal to its average speed?

Answer 1

If the motion of an object is along a straight line and in the same direction, the magnitude of displacement is equal to the total path length. In that case, the magnitude of average velocity is equal to the average speed.

Answer 2

The magnitude of average velocity of an object will be equal to its average speed in the condition of uniform velocity in a straight line motion.
